NM93CS06L/CS46L/CS56L/CS66L 256-/1024-/2048-/4096-Bit Serial EEPROM with Extended Voltage

(2.7V to 5.5V) and Data Protect (MICROWIRE Bus Interface)

NM93CS06L/CS46L/CS56L/CS66L

March 1997

NM93CS06L/CS46L/CS56L/CS66L

256-/1024-/2048-/4096-Bit Serial EEPROM

with Extended Voltage (2.7V to 5.5V) and Data Protect

(MICROWIRE

™

Bus Interface)

General Description

The NM93CS06L/CS46L/CS56L/CS66L devices are 256/

1024/2048/4096 bits, respectively, of non-volatile electrically

erasable memory divided into 16/64/128/256 x 16-bit regis-

ters (addresses). The NM93CSxxL Family functions in an

extended voltage operating range, and is fabricated using

Fairchild Semiconductor’s floating gate CMOS technology

for high reliability, high endurance and low power consump-

tion. N registers (N

≤

16, N

≤

64, N

≤

128, N

≤

256) can be

protected against data modification by programming the Pro-

tect Register with the address of the first register to be pro-

tected against data modification. (All registers greater than,

or equal to, the selected address are then protected from fur-

ther change.) Additionally, this address can be “locked” into

the device, making all future attempts to change data impos-

sible.

These devices are available in both SO and TSSOP pack-

ages for small space considerations.

The serial interface that controls these EEPROMs is MI-

CROWIRE compatible, providing simple interfacing to stan-

dard microcontrollers and microprocessors. There are a total

of 10 instructions, 5 which operate on the EEPROM memory

and 5 which operate on the Protect Register. The memory in-

structions are READ, WRITE, WRITE ALL, WRITE EN-

ABLE, and WRITE DISABLE. The Protect register instruc-

tions are PRREAD, PRWRITE, PRCLEAR, PRDISABLE and

PRENABLE.

Features

Sequential register read

Write protection in a user defined section of memory

2.7V to 5.5V operating range in all modes

Typical active current of 200 µA; typical standby current

of 1 µA

No erase required before write

Reliable CMOS floating gate technology

MICROWIRE compatible serial I/O

Self timed write cycle

Device status during programming mode

40 year data retention

Endurance: 10

data changes

Packages Available: 8-pin SO, 8-pin DIP, and 8-pin

TSSOP
